Letters Patent No. 63,536, dated Apo-Z 2, 1867.`

"' IMPROVBD scArroLD.

TO ALL WHOM IT MAY GONCERN Be it known that I, HORAE LITTLEFIELD, of Lewis, Cass county, Iowa', have invented an Improved Scaffold; and I do herebyl declare that .the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in whieh Y Figure 1 is a side elevation of niy improved scaffold.

Figure 2 is a. front view of` the saine.

Fig-ure 3 isa plan or top View of the same showing it folded up.

Figure 4 is a side view of' the extension-leg; and

Figure 5 is an edge view of thc same partly in section.

Similar letters of' reference indicate corresponding parts.

This invention relates to certain improvements on the scaffold for which Letters Patent were granted to me on the 8th day of August, 1865; and the invention consists in such an arrangement of the parts described in the aforesaid Letters Patent, that I am thereby enabled to sot this scaffold up independently; not requiring to lean it against a building or wall. By this arrangement this scaffold is applicable. for pl'asterers work espe. cially, and f'or all work to be performed on the ceilings of' rooms; and also in gardens t0 be set under trees for various purposes.

By referring to the drawings, it will be observed that this scaffold is an exact duplicate of' the one patented; in fact two such sea'lfolds, instead of being leaned against the Wall of' a building, are leaned against cach other, and are then secured together -by nieans of` bolts, old, or in any other suitable manner. The construction is substantially the saine. rlhe timbers A B, and the braces a b, the adjustable legs C C, the stanchions c e, and the railing E, are all arranged on the same principle, but only in double quantity on each scaffold. The side supports, consisting of the bars A A, B B., and braces a :1,71 b, may or may not be .so secured together as to be taken apart. In fig. 3, one such support is represented asuiade together, -and it is thus ready for transportation with the platform D, and all the other portions. The legs C may be extended by the contrivance shown in figs. L and 5. In this the piece E is secured to the lez- 1,t C by means of two (more or less) links, c e, fitting into grooves in the leg and attachment, as shown. As this scaffold has to stand free, without leaning against any substantial structure, it is advisable to use the ladders by which the platform is reached as further means of' support or as braces. Thus the ladders G G are used to brace the platform from the side, as shown. They are also provided with pointed ends as shown in the drawing.

I claim as new, and desire to secure by Letters Patent- A portable scaffold that is made substantially as and'f'or the purpose herein shown and described.
